PUMP.

Application filed April 15, 1914.

To (6% whom it may concern:

Be it known that we, CARL J. VELEY and LINCOLN S. DEAL, citizens of theUnited States, residing at Kalamazoo, Michigan, have invented certainnew anduseful Improvements in Pumps, of which the following is aspecification.

This invention relates to improvements in pumps.

The main objects of this invention are: First, to provide an improvedpump which is especially desirable for use in pressure systems. Second,to provide in a motor pump an improved pumping jack. Third, to providean improved motor pump structure adapted for pumping both hard and softwater which is automatic in its operation. Fourth, to provide animproved pump which is very quiet in its operation. Fifth, to pro videan improved motor pump in which the driving connections are so arrangedthat the strains are balanced and friction minimized. Sixth, to providean improved motor pump which is very compact and is comparatively simpleand economical in structure.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and meansdescribed in the following specification. I

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the pump cylinder 1 is arranged within thewell and is shown, as is quite common portion of the well pipe. Theplunger 2 of this cylinder 1 is provided with a ball check valve 3. Acheck valve 4 is provided below the plunger 2. On the upper end of thewell pipe is a cylinder 5. The cylinder 5 is of larger area than thecylinder 1, the object of which will appear later. A piston 6 isprovided for the cylinder 5.

The piston 6 is connected to the plunger 2 by means of the pump rod 7 sothat the plunger and piston reciprocate together. The pump rod 7 isextended through the top of the cylinder 5 and connected to the crosshead '8. The piston 6 is provided with a .downwardly opening check valve9 which opens on the upstroke of the piston and closes on itsdownstroke, being held yieldingly on its seat by means of the springlO.

The upper end of the cylinder 5 is provided with an air inlet valve 11which is practice, as :1

arms for the uprights.

opened. by the downstroke of the piston 6 to admit air to the cylinder 5above the piston. This valve is closed on the upstroke of the piston sothat the air passes through the valve 9 into the cylinder below thepiston. The valve 11 is held yieldingly on its seat by means of thecoiled spring 12. vent cock 13 is provided for the upper end of thecylinder. When this vent cock is opened air enters and passes from thecylinder above the piston as the piston reciprocates. The cylinder 5 isconnected to the storage reservoir 1 1 by means of the pipe 1 5, thetank and connections being shown: in conventional form in: Fig. XV. I

The pipe 15 is provided with a check valve 1-6. On the upstroke, wateris lifted by the plunger 2 into the. cylinder 5, and since the cylinder5 is ofgreater diameter than the cylinder 1, air passes thevalve 9. Onthe downstro-ke, the air andwater is forced out of the cylinder 5 pastthe valve 16 into the tank 1 1. The air in the cylinder 5 below thepiston serves as acushion. preventing shocks and. noise as the pistonsmove downwardly. \Ve thus secure a combined air and water pump which.maintains the desired pressure in the tank 1 1.

The cross head 8 is mounted to reciprocat-e upon. the front uprights 17of the jack frame. The rear uprights 18 of the jack frame are supportedby-a suitable'floor plate 1 9 having sockets rights.- The uprights 17and 18' are connected by the H shaped horizontal frame members 22 havingholes at the ends of their These uprights are preferably sections ofpipe, as shown, and the frame members 22 are secured thereon by means ofset screws 23.

The well pipe 26 serves as an anchor and support for the pump frame. Theshafts for the driving and crank wheels are supported by a frame member27 which constitutes the bottom: horizontal frame member of the jackframe. The member 27 is secured to the well pipe 26'- by means of aclamp comprising clamp members 28 and the clamping bolt 28. The uprights18 extendthrough the frame member 27, which is secured thereto by setscrews 24:. The crank wheel shaft 29 extends through member 27, therebeing a crank wheel- 30 on each end of the shaft. The pitman orconnecting rods 31 are connected to the crank wheels by suitable crankor wrist pins 32. To regulate the stroke of the pump, the crank wheelsare provided with a plurality of wrist pin bearings ferent distancesfrom the shaft.

The driving wheel 3% is connected to the crank wheels by means of thebelts 35, the hub of the driving wheel being provided with pulleys orbelt wheels 36 for these belts' Belt tighteners are provided for the 21therein for the up-' the frame 33 positioned at difthe wheel- 3a. A belttightener is provided for the belt ll, the belt tightener consisting ofa pulley if carriedbv the. forked arm 45 r which:ismounted on the shaft80, asare the arms 38:. By this arrangement of. the parts described, wesecure a. very compact and sim'ple'structure. V

The soft water pump cylinder 18 is supported by a pair of bracketsextending between the uprights 17. These brackets consist of a pair ofmembers 429 clamped together upon the pump cylinder 18 and theuprightsby. the bolts 50. The plunger 51 forthe cylinder as is providedwith a pump rod which isco-nnccted to the cross head .8; Thusconnected-,1 the pumps arezoperated together. The cylinder 18' isconnected to the soft water pressure or storage by the pipe 54,-see Fig.XV-and to the cistern or supply 55 by the pipeeo. .The pipe 56 isprovided with a check valve 5T shown conventional-1y only, the checkvalve being disposed between the supply and the connection of the pipe54to the cylinder es. The pipe 541 is provided with a check valve 58controlled bv an electromagnet, the valve stem 59 constituting thearmature of such electromagnet. See Fig. XVI. pressure is suppliedtothe-tank 53 through the pipe 60 connecting the tank 53 with the tank14;. A return check. valve 61 is provided for the pipe 60.

The electric motor 40 is-controlled by the switch 62 operated by the"heat 63 in the pressure tank 14;, the switch 62'being opened by therising of the float when the tank is substantially filled, thus stoppingthe motor, the switch being connected to themotor through; the circuits6%. hen the water withinthe tank 14; fallsbelow apredetermined point,the float falls, closing the switch 62 and starting the; motor. Theplunger 51 is,

tank 53' Air under 7 of course, owing to its connection to thecross-head, operated whenever the cross head 8Eis operated,

The soft water pump lsrenderedinoperatlve for pumping water by theopening-of the valve58 in 'theconnection-M: for the reai son that, whenthis valve is opened, the water travels-from the cylinder 4:3 into thepipe 54 andback to t "6' cylinder as the plunger reciprocates. The,valve 58 is auto; matically held open by the electromagnet,

the delivery of current to the magnet being controlled by the float inthe tank 53 which operates the switch 66 of the circuit 67, the switchbeing open when the water within the tank is below a predetermined pointand closed when it is at this point. lVith the parts thus arranged, whenthe Water fills the tank 53 to the desired point, the float operates toclose the switch and the clectromagnet is thus operated to hold thevalve 58 in its open position, thereby rendering the soft water pumpinoperative as the water merely passes from the cylinder into the pipeas and vice versa. A safety valve 68 is provided for the tank 53, the

safety valve being automatically opened, al-

lowing the air to escape,.when the pressure within the tank exceeds apredetermined point. The water is drawn from the tanks through the housesystems 69 and 70, which are shown only in conventional form in Fig. XV.lVhere an alternating current is used the electromagnet is preferablysupplied through the induction coil 71 connected to the motor circuits64.

To lubricate the crank pins 32 and the crank wheels 30, the wheels areformed with oil chambers '75 which embrace the crank pins and also theends of the shaft :29. The shaft is formed hollow and provided withlubricant openings 76 communicating with the oil chamber 75. See Fig.III. The idle bearings 33 for the crank pins are closed by plugs 77which prevent the escape of lubricant from the lubricant chamber 75. Theoil is introduced through the shaft which is provided with an oil hole78. See Figs. II and IV. By providing this lubricating means for thebearings, very little attention is necessary. The driving wheel 34 islubricated by providing its hub with a chamber 79 which is filled with asuitable absorbent material adapted to retain the lubricant. The shaft80 is supported on the arms 81 of the frame member 27, the arms havingholes 82 therein for the shaft. See Fig. VII. Set screws 83 clamp theshaft against the spaced rest Between the arms 81 and the ends of thehubs are thrust collars 85 which are flared at their inner ends as at86. The ends of the hub of the driving wheel are chambered to receivethe flared ends of these collars and provided with oil openingsconnecting the chambers and the oil reservoir. The chambers are expandedi11- wardly and the oil passages are disposed so that the centrifugalforce tends to carry the lubricant back into the oil chamber 79.

Eur improved pump is automatic in its operation, and is substantiallynoiseless and without vibration, which is a feature of very greatadvantage as it is especially designed for use in residences althoughadvantageous for use elsewhere. The pressure is automatically maintainedethat is, air

and waterare simultaneously pumped if desired-so that the water is underpressure and may be delivered to any part of a house system as desired.

We have illustrated and described our improved pump in a practicalembodiment. lVe have not attempted to illustrate or describe variousmodifications which we contemplate, as we believe the disclosure madewill enable those skilled in the art to which this invention relates, toembody or adapt the same as may be desired to meet the particularconditions. We desire, however, to be understood as claiming ourimprovements specifically in the form illustrated as well as broadlywithin the scope of the appended claims.

Having thus described our invention what we claim as new and desire tosecure by Let ters Patent is:
